Abstract:
A method for generating an image of an object is provided. The method comprises acquiring projection data at one or more projection views along a circular scan trajectory and generating a corrected projection dataset based upon a weighted derivative applied to a subset of the projection data. The method further comprises backprojecting the corrected projection dataset along one or more projection rays associated with one or more of the projection views, to generate a reconstructed image of the object.
